The in situ generation of alk-1-ynyllead triacetates from terminal acetylenes by zinc-lead exchange and crystal structure of 2,4,7,9,13-pentamethyl-9-phenylethynyl-7,10-ethenospiro[5.5]undeca-1,4-diene-3, 8-dione

Methods involving zinc-lead exchange for the one-pot conversion of terminal acetylenes into alk-1-ynyllead(IV) triacetates have been developed, and examples of the in situ C-alkynylation of a number of carbon nucleophiles are reported. An attempt to extend the reaction to phenols by treating 2,4,6-trimethylphenol with phenylethynyllead triacetate led to formation of the spiro dienone 16, the structure of which was determined by X-ray diffraction.

'ALK-1-YNYLLEAD TRIACETATES' AS ALK-1-YNYL CARBOCATION EQUIVALENTS. THE α-ALK-1-YNYLATION OF β-DICARBONYL COMPOUNDS AND NITRONATE SALTS.

The addition of lead tetraacetate to a chloroform solution of alk-1-ynyltrimethylstannane results in the rapid formation of trimethylstannyl acetate and an unstable species, believed to be the corresponding alk-1-ynyllead triacetate, which can effect the rapid α-alkynylation of β-dicarbonyl compounds and nitronate salts.
